THe E92 would be much more convenient becasue it's in the same province that I am in so no need to pass a safety for "importing" the vhiecle.

My only concern is reliability. I have read stories about rod bearing issues on both vehicles. Also after seeing how you change a light bulb in the E9X, I am scared that DIY on the E9X is more complicated, although I am up to the task.

And personally, I love the V8 sound more. But I am not rich and also would like to know what to expect if there is a major difference in cost for maintenance.

I've never had an E46 M3, but I do have an E90 M3. Rod bearings in the E90 M3 are and are not an issue. Many have driven for over 100k miles with no problems. If you're worried like I was, factor in $2-3k and have them changed. Other than that, the other expensive thing to consider is throttle actuators. They appear easy to install, but they're pricey. I've done some work on my car (like the HID bulb) and it's not particularly difficult. Other things will have you searching for a good independent shop.

From what I've read the E46 M3 has more potential issues: VANOS, subframe cracks. Either way, you'll have a fantastic car.
